A Wisconsin boy is being hailed for his quick-thinking for helping save his pop from a heroin overdose, according to a report.

The 8-year-old child, identified only as “Christopher,” told the 911 dispatcher that his father was “not waking up or anything” during his desperate Thursday night phone call from inside a car parked near a school in Waukesha – a suburb of Milwaukee, CBS affiliate WDJT-TV reported.

His passed out father was slumped behind the wheel with two other siblings in the vehicle, the TV station said.

“I think my dad is dead,” the boy told the dispatcher.

When the dispatcher asked for their whereabouts, Christopher struggled to answer, saying, “There’s a lot of trees.”

A Good Samaritan who happened to be passing by took charge of the situation, giving the dispatcher their exact location.

“The father is in the driver’s seat slumped over, not responding to anything, so I don’t know what’s going on,” the man said. “ … doesn’t look good. If you could get someone here, that would be great,” WDJT-TV reported.

Police raced to the scene and removed the drugged up dad from the car.
